To ALL PERSONS To WHoM THESE PRESENTS MAYy coME= Be it known that I,CHARLES WILLIAMS, of Manchester, in the`coi1-nty of Hillsboro, andAState of New .Hampshire have ,invented a new and useful Improvement inEStoves made of Soapstoue and Iron; and I do ingI drawings, of which-Figure 1 is a vertical section, Figure 2 a horizontal section, Figure 3a front elevation, and Figure 4 a rcarelevation of a stove provided withmy invention. This stove is what is termed avsoapstonepanelled stove, itbeing composed of a metallic frame and sundry 'herebyy declare the sameto be fully described in the following specification, and represented inthe accompany- V,panels or plates of scapstone fixed therein.

The bottom part -.A.- of 'the frame is a hollow case or box, made ofiron, and with a ange, a, projecting from tsuppcr surface. There is alsoan opening,f'd,= through the top of the case A, t-o lead smoke from thefrout flue cinto such case. Another opening, d, in the top of the caseA, serves to conduct the smoke up into a stand-pipe, B, erected on thecase, and arranged in r'earof `the stove-body, and made to open into acase or box, C, fixed to the `back of the stove. This box Cfhas akettlc-hole, e., in its top. It also has an ai'r-register, l

d', applied Ato its rear, and,=underneath,a discharge-neck, f, on whichthe pipe te conduct the sm/)ke'to the chimney is to be fixed. A hole, g,through the back plate of the stove, leads the smokeinto the ease C.Within such case C a dampershould be placed, and arranged so'as toenable a person, by turning such damper, to cut o' direct communicationbetween the chamber of' combustion and the escape-pipe, so as to causethe smoke to pass down thelfi'ont Hue c, and into the caseA, thence upthe stand-pipe, and thence into the case C andthe escape-pipe. I v l iThe body of the stove is composed of the caseA, a recessed cap, D, aseries of rebated posts, E E, and a lseries of soapstone panels, F F FF,G G G G, H H H H, such panels being arranged between the posts, and inthe rebates thereof. i The `two front posts are grooved, as shown at z'z', to receive'and hold a vertical plate, I, of so'apstoue, whichextends some distance up from the vtop of the-case A, and serves, notonly as an inner lining to protect the fronttplate of thestove from thefire, bnt'as a means of forming, with such front plate and the twosupporting posts, a descending `ln`e,"e. Each pair of next adjacentposts supportin their rebates two soapstone panels, G H.

` whole constituting a stove, substantially as set forth.

'lherebates lc, for holdingeaeh o f the outerplates F andH, are4 formedso as to enable such plates to be either inserted in placeor removedthence from the outside of the stove. The base part, the cap-plate,` andthe post sjarc held together by screw-rods K, which vare carried down inchambers' or spaces L, made between each pair of the plates G and H, thepurpose of the inner plates G being to protect the connecting-rods fromVy the fire, while that off the plates H is to cover them from` sight.Tlre plates F and- H are held in their rebates or pinces by slottedlapping-plates'M, whose ends are overlapped by the flanges a andm of thebase and cap.

plates. Each of the lapping-plates M extends across and beyond thesoapstone panel' H, against which it rests, and laps over the adjacentedge of Ithe n'exrtadjacent son-pstone panel F, so as to cover thejoints between thorn and the next adjacent posts. v

w My arrangement of panels, posts lap-plates, cap-plate, and baseenables either of the lap-plates, 4or either ofthe panels, to be easilyremoved from its place, and another substitnted,vwhen, by unequalexpansion of any` of such lpartner by other cause, such part may becomecracked or injured, it will be an easy matter toremove it, vand supplyits place with a fresh or whole substitute, tvithout rendering itnecessary to-dsarrange the connection of the parts composing themetallic frame ot the stove, except it may be to simply unscrew the nutsof such connection. 'l

I claim the combination ofthe lue-platelf, the flue c, the case.A, thestand-pipe B, andthe air and smokebox C, with the rebated posts E, thecap D, the series ci' soapstone panels F G H, and the lap-plates M, the
